Details

The storage life of industrial sealing rings is determined by the type of rubber material and storage conditions. So under conventional storage conditions, the shelf life of sealing rings made of different materials also varies. For example:
1. Polyurethane and thermoplastic materials for 4 years;
2. Nitrile rubber, hydrogenated nitrile rubber, and chloroprene rubber for 6 years;
3. Ethylene propylene rubber for 8 years;
4. Fluorine rubber, silicone rubber, and fluorosilicone rubber for 10 years;
5. Perfluorinated rubber for 20 years;
6. Polytetrafluoroethylene indefinitely.
After the above deadline, the characteristics of the sealing ring should be checked before use, and it can still be used for a period of time while maintaining its original characteristics.
But if the sealing ring ages, it cannot play its due role and can only be replaced.
There are many types of silicone rubber materials, each with different properties and usage scenarios. It's not just about using a sealing ring casually. It's best to understand the temperature, pressure, oil or chemical substances in contact, and the merchant will also recommend a suitable sealing ring for you. If an inappropriate industrial sealing ring is used, it not only fails to achieve the desired sealing effect, leading to frequent replacement, but may even reduce the lifespan of the machine and pose a threat to production equipment. So although the sealing ring is just a small ring, its function cannot be underestimated.
